PYTHON Who could help

Question

I wanna write a program by python that calculates who many times each type of characters occur in a given string.
string is heeeeellllooooooworlddd for example

Answer 1

A quick solution is to use the collections module. Example:

import collections
import pprint
string = input('Enter string: ')
count = collections.Counter(string.lower())
value = pprint.pformat(count)
print(value)

Answer 2

Another way to do it, without using any modules is by using dictionaries.

If you want to consider the lower-case and upper-case letters differently, then you can use this code:

dict = {}
string = input("Enter string: ")

for x in string:
    if x in dict:
        dict[x] += 1
    else:
        dict[x] = 1
print (dict)

 If the case doesn't really matter, then you can use this code:

dict = {}
string = input("Enter string: ")

string = string.lower()

for x in string:
    if x in dict:
        dict[x] += 1
    else:
        dict[x] = 1
print (dict)

You can use the following code:

from collections import Counter
inp_string=input("Enter your string\n")
lis=list(inp_string)
length=len(inp_string)
cnt = Counter()
for i in lis:
     ls= set(i)
     for l in ls:
          cnt[l] +=1
print (cnt)
